    IN THE UNITED STATES COURT OF APPEALS
    FOR THE FIFTH CIRCUIT

    Petitioner-Appellee Cross-Appellant
    v.
    RICK THALER, DIRECTOR, TEXAS DEPARTMENT OF CRIMINAL
    JUSTICE, CORRECTIONAL INSTITUTIONS DIVISION
    Respondent-Appellant Cross-Appellee
    Appeal from the United States District Court
    for the Southern District of Texas
    Before KING, DENNIS, and OWEN, Circuit Judges.
    KING, Circuit Judge:
    The petitioner–appellee, Anthony L. Pierce, was sentenced to death in
    1986 in Texas state court for a murder committed during the course of a robbery
    in 1977. After exhausting his state-court avenues for postconviction relief in
    2007, he sought habeas relief under 28 U.S.C. § 2254 in federal district court.
    The district court vacated Pierce’s death sentence and ordered resentencing,
    finding that the statutory special issues presented to the jury at Pierce’s
    sentencing did not permit the jury to give meaningful consideration and effect
    to all of Pierce’s mitigating evidence, as Penry v. Lynaugh, 
    492 U.S. 302
    (1989),
    No. 08-70042
    requires. The district court denied Pierce’s other asserted bases for habeas relief
    and denied a certificate of appealability (COA).        The State appealed the
    resentencing. Pierce, in turn, sought a COA from this court on six of the issues
    raised before the district court. We granted a COA as to two of those issues:
    Whether Pierce received ineffective assistance of counsel at sentencing, and
    whether Pierce was mentally retarded and therefore ineligible for the death
    penalty under Atkins v. Virginia, 
    536 U.S. 304
    (2002).
    We now affirm the district court’s grant of resentencing under Penry.
    Because we affirm resentencing on that basis, we do not address whether
    Pierce’s ineffective assistance of counsel claim provides an alternate basis for
    resentencing. We affirm the district court’s denial of habeas relief and an
    evidentiary hearing on Pierce’s Atkins claim. The reasons for these rulings are
    explained below.
    I. BACKGROUND
    The district court’s exhaustive opinion more than adequately documents
    the factual background and procedural development of this case. See Pierce v.
    Quarterman, No. H-07-1561, 
    2008 WL 4445064
    (S.D. Tex. Sept. 26, 2008). Here,
    we recite only the facts and procedure necessary to our analysis of the Penry and
    Atkins claims.
    Anthony L. Pierce was convicted of capital murder for the shooting death
    of Fred Eugene Johnson, the manager of a Church’s Chicken in Houston, during
    a robbery of that restaurant on August 4, 1977. Pierce’s first two convictions
    were overturned by the Texas Court of Criminal Appeals (TCCA), in both cases
    because the trial court had improperly overruled defense counsel’s challenges to
    certain venire members. See Pierce v. State, 
    604 S.W.2d 185
    (Tex. Crim. App.
    1980); Pierce v. State, 
    696 S.W.2d 899
    (Tex. Crim. App. 1985). Pierce was tried
    and convicted a third time and sentenced to death in 1986. The TCCA affirmed
    the conviction and sentence, Pierce v. State, 
    777 S.W.2d 399
    (Tex. Crim. App.
    2
    No. 08-70042
    1989), cert. denied, 
    496 U.S. 912
    (1990), and denied his application for
    postconviction relief, Ex parte Pierce, No. 15,859-03 (Tex. Crim. App. Sept. 19,
    2001). On August 29, 2002, Pierce filed a successor state habeas application in
    which he contended that he was mentally retarded and therefore ineligible for
    the death penalty under Atkins. The TCCA denied the application on April 18,
    2007. Ex parte Pierce, No. 15,859-04, 
    2007 WL 1139414
    (Tex. Crim. App. Apr.
    18, 2007). Pierce filed a 28 U.S.C. § 2254 federal habeas petition on May 9, 2007,
    an amended federal habeas petition on August 30, 2007, and a supplemental
    federal habeas petition on July 1, 2008.
    On cross-motions for summary judgment, the district court granted Pierce
    habeas relief on one of his sentencing claims, concluding that the special issues
    presented to the jury at the sentencing phase did not permit the jury to give
    meaningful consideration and effect to all of Pierce’s mitigating evidence, in
    violation of Penry. The district court denied the remaining asserted bases for
    habeas relief and sua sponte denied a COA on those issues. See Pierce v.
    Quarterman, 
    2008 WL 4445064
    . We granted a COA as to Pierce’s claims that
    he received ineffective assistance of counsel at the sentencing phase and that
    because he is mentally retarded, his execution is precluded by Atkins. We
    ordered (and have received several rounds of) supplemental briefing as to these
    issues and denied a COA as to all other issues.
    II. STANDARD OF REVIEW
    This habeas proceeding is subject to the Antiterrorism and Effective Death
    Penalty Act (AEDPA), 28 U.S.C. § 2254, because Pierce filed his federal petition
    on May 9, 2007, well after AEDPA’s effective date. See Lindh v. Murphy, 
    521 U.S. 320
    , 336–37 (1997). Under AEDPA, a federal court may not grant a writ of
    habeas corpus “with respect to any claim that was adjudicated on the merits in
    State court proceedings” unless the state court’s adjudication: “(1) resulted in
    a decision that was contrary to, or involved an unreasonable application of,
    3
    No. 08-70042
    clearly established Federal law, as determined by the Supreme Court of the
    United States; or (2) resulted in a decision that was based on an unreasonable
    determination of the facts in light of the evidence presented in the State court
    proceeding.” 28 U.S.C. § 2254(d). A “rule[ ] of law may be sufficiently clear for
    habeas purposes even when [it is] expressed in terms of a generalized standard
    rather than as a bright-line rule.” Williams v. Taylor, 
    529 U.S. 362
    , 382 (2000).
    The relevant “clearly established federal law” is the law that existed at the time
    the state court’s denial of habeas relief became final. See Abdul–Kabir v.
    Quarterman, 
    550 U.S. 233
    , 238 (2007); 
    Williams, 529 U.S. at 390
    –94. A state
    court’s factual findings are “presumed to be correct,” although a habeas
    petitioner may rebut this presumption by “clear and convincing evidence.” 28
    U.S.C. § 2254(e)(1). We review a district court’s refusal to hold an evidentiary
    hearing for abuse of discretion. Clark v. Johnson, 
    202 F.3d 760
    , 765–66 (5th Cir.
    2000).
    III. THE PENRY ISSUE
    The district court vacated Pierce’s death sentence and ordered
    resentencing after concluding that the statutory special issues presented to the
    jury at sentencing and the prosecutor’s closing arguments regarding those
    special issues precluded the jury from giving meaningful consideration and effect
    to all of Pierce’s mitigating evidence, as Penry requires. Pierce, 
    2008 WL 4445064
    , at *5. The State appeals, arguing that the special issues in fact
    permitted the jury to give meaningful consideration and effect to the mitigating
    evidence. The special issues, as prescribed by a now-superseded version of the
    Texas Code of Criminal Procedure, were:
    1)    Whether Pierce’s conduct that caused Johnson’s death was
    deliberate and undertaken with the reasonable expectation
    that the death of the victim or another would result; and
    4
    No. 08-70042
    2)     Whether there was a probability that Pierce would commit
    future criminal acts of violence that would constitute a
    continuing threat to society.
    See TEX. CODE CRIM. PROC. ANN., art. 37.071(b) (Vernon 1981);1 see also TEX.
    CODE CRIM. PROC. ANN., art. 37.0711 § 1 (Vernon 2006) (noting that superseded
    statute applies to offenses committed before September 1, 1991).
    A.     The District Court’s Opinion
    The district court summarized the mitigating evidence that Pierce
    presented at sentencing as including that: Pierce was young at the time of the
    crime (he had turned eighteen just 15 days before); his behavior in prison while
    incarcerated at various points both before and after the crime was generally
    good; he was not a discipline problem as a child and was honest and respectful
    toward his mother and admitted past wrongs to her; he had matured emotionally
    and spiritually while in prison; and he had developed intellectually and
    creatively while in prison, improving his verbal abilities and making crafts, such
    as picture frames and jewelry boxes. Pierce, 
    2008 WL 4445064
    , at *2. The
    district court rejected as unreasonable the TCCA’s conclusion that the special
    issues permitted the jury to give meaningful consideration and effect to this
    mitigating evidence. Noting that “Penry makes clear that jurors must have an
    opportunity to fully consider the mitigating evidence as it bears on the broader
    question of the defendant’s moral culpability,” 
    id. at *5
    (alterations and internal
    quotation marks omitted), the district court observed:
    On the face of the special issues, the jury could consider some
    of Pierce’s evidence under the future dangerousness special issue.
    1
    Pierce properly preserved his objection to the special issues, arguing at the sentencing
    phase that they did not permit the jury to give meaningful consideration and effect to the
    mitigating evidence. Pierce requested, but was denied, the following jury instruction:
    You are hereby instructed that you can consider all mitigating circumstances in
    regards to the punishment of the defendant herein. Mitigation will not be
    defined for you; but you may consider the age, race, background, sex, history,
    and all matters related to this defendant that have been put before you.
    5
    No. 08-70042
    For example, Pierce’s youth at the time of the offense and his
    behavior in prison are relevant to that issue. Other evidence,
    however, is irrelevant, or is only partially relevant, to the future
    dangerousness issue, yet raises questions about Pierce’s general
    moral culpability and character. For example, his honesty and
    respect toward his mother, his willingness to admit past wrongs, his
    efforts to improve himself through education, and his work making
    craft items have little relevance to future dangerousness, but are
    relevant as to his character.
    
    Id. (citations omitted).
           The district court also held that the “Penry violation was exacerbated by
    prosecution comments during closing argument,” which the district court found
    “suggest[ed] to the jury that it could not consider Pierce’s mitigating evidence at
    all . . . but could consider only whether the State presented sufficient evidence
    to merit a ‘yes’ answer to the special issues.” 
    Id. The district
    court concluded
    that “the special issues in this case, especially when considered in light of the
    State’s closing argument, violated Pierce’s rights under Penry.” 
    Id. at *6.
    Accordingly, the district court vacated Pierce’s death sentence with instructions
    that the state court grant a new sentencing hearing or resentence Pierce to a
    sentence less than death in accordance with Texas law in effect at the time of
    Pierce’s crime.
    B.     Pierce’s Additional Mitigating Evidence
    Pierce contends that additional mitigating evidence that he presented at
    sentencing and raised in his state habeas application and federal habeas
    petition, but that the district court did not discuss in its Penry analysis, provides
    further support for the district court’s conclusion.2 Pierce cites the testimony of
    2
    Pierce contends that there was substantial mitigating evidence that his trial counsel
    did not present at sentencing. This evidence included that Pierce: was borderline mentally
    retarded; was severely abused by his alcoholic father; grew up in extreme poverty in a violent
    neighborhood; and suffered from “horrific headaches” and other health problems as a child.
    Counsel’s failure to present such evidence, however, does not provide a basis for a Penry claim,
    and Pierce does not urge this evidence in support of his Penry claim. “[W]e have held that a
    6
    No. 08-70042
    his mother, Erline Pierce, that he was a good child with few behavioral problems
    until he was 13 or 14 years old, when he fell in with a crowd of older boys who
    exerted a bad influence. Erline Pierce further testified that, as a result of this
    corrupting influence, Pierce was sent to the Texas Youth Council (TYC)3 twice
    for extended juvenile detention stays as a young teenager. She commented that
    Pierce had been “locked up most of his young life,” so he “couldn’t have a
    chance.” Erline Pierce testified that her son had regularly attended church
    growing up and “still ha[d] those same beliefs” after his arrest. Finally, Erline
    Pierce testified that her son had emotionally matured and improved himself in
    prison by furthering his education, developing his reading skills, and developing
    his talent for art and woodworking by making jewelry boxes and picture frames
    for her.
    Pierce also cites the testimony of Sister Isabella Estrada, a principal for
    Holy Cross School in Bay City, Texas. Sister Estrada testified that she got to
    know Pierce during his years on death row, and she visited him regularly in the
    four years leading up to Pierce’s third trial. She testified that Pierce grew from
    being depressed and angry about his situation to being more understanding. As
    he developed his ability to speak and articulate his thoughts, Pierce became
    more open and able to communicate his feelings.
    Pierce also cites comments by the prosecutor during voir dire that he
    asserts “conditioned” the prospective jurors to disregard his mitigating evidence.
    In one such instance, the prosecutor stated:
    petitioner cannot base a Penry claim on evidence that could have been but was not proffered
    at trial.” Miniel v. Cockrell, 
    339 F.3d 331
    , 338 (5th Cir. 2003) (internal quotation marks
    omitted).

    The Texas Legislature changed the name of the Texas Youth Council to the Texas
    Youth Commission in 1983.           See Texas Youth Commission, TYC History, at

    No. 08-70042
    Q.    Would you also agree that under our law that the age of an
    individual, whether that be old or young age, in and of itself does
    not give anyone any special rights? Under our law when a person
    becomes the age of 17 they are an adult and are treated as such.
    Would you agree?
    A.   Yes, sir.
    Q. Okay. So in that instance whether a person is 17 or they’re 85,
    the law doesn’t ask how old you are, what color you are, what your
    job is, what your sex is, what your education is, it asks that you
    follow certain norms and those norms determine the interaction
    between human beings and violation of those be tried by a jury if it
    be a criminal. Can you follow that concept in the purposes of our
    law?
    A.   Yes, sir, I believe so.
    The prosecutor also sought and obtained the juror’s oral confirmation that if the
    juror concluded that the answer to the two special issues was “yes,” he would not
    “change one of those answers to no just to prevent the defendant from receiving
    the death sentence.”
    Similarly, to another prospective juror, the prosecutor asked:
    Q.      Now, would you agree with me . . . that our law doesn’t
    distinguish as far as finding someone guilty in the law as it relates
    to an individual on the basis of their age or sex, their race or ethnic
    background? . . . I’m saying that our law, as far as making a person
    guilty or being charged with capital murder—like that doesn’t
    distinguish whether or not that person happens to be 17 or 18 or
    black or white or a doctor or what I’m saying is race, sex,
    occupation, ethnic background, as far as whether or not they violate
    the law.
    A.   I agree.
    Q. And would you feel that if the State presented evidence to you
    on Special Issue No. 2 that was beyond a reasonable doubt that the
    answer to Special Issue No. 2 should be “yes” and you found that
    perhaps that individual was a particular age, a young person or so,
    8
    No. 08-70042
    would you necessarily answer that question “no” because of the age
    or despite what the State showed you?
    A.    No.
    The State contends that the Texas special issues in fact permitted the jury
    to give meaningful consideration and effect to all of the mitigating evidence
    presented and rejects the proposition that any of the prosecutor’s comments
    during voir dire or closing argument could have interfered with the jury’s ability
    to do so.
    C.     The Legal Framework
    1.     Abdul–Kabir and Brewer
    The Supreme Court most recently addressed the Texas special issues in
    Abdul–Kabir, 
    550 U.S. 233
    , and Brewer v. Quarterman, 
    550 U.S. 286
    (2007).4
    These cases describe the “clearly established law” as it existed in 1999 and 2001,
    4
    Abdul–Kabir and Brewer clarified a long and contentious line of cases in which the
    Court grappled with whether the Texas special issues provide a basis for the jury to give
    meaningful consideration and effect to mitigating evidence in considering a death sentence.
    See Jurek v. Texas, 
    428 U.S. 262
    (1976) (upholding the facial constitutionality of the Texas
    special issues sentencing scheme but leaving room for as-applied challenges); Franklin v.
    Lynaugh, 
    487 U.S. 164
    (1988) (rejecting as-applied challenge, reasoning that evidence of good
    prison behavior did not have mitigating significance independent of its relevance to the future
    dangerousness special issue); Penry, 
    492 U.S. 302
    (concluding that habeas relief was
    appropriate because the special issues did not provide a basis for jury to give meaningful
    consideration and effect to evidence of low IQ, organic brain disorder, abusive upbringing, and
    antisocial personality disorder); Graham v. Collins, 
    506 U.S. 461
    (1993) (declining to decide
    whether Texas special issues could give constitutionally adequate effect to mitigating evidence
    of good character and youth because law was not clearly established in 1984, when the
    conviction become final); Johnson v. Texas, 
    509 U.S. 350
    (1993) (concluding, on direct review,
    that the petitioner’s youth at the time of the crime could be given meaningful consideration
    and effect under the future dangerousness special issue); Penry v. Johnson, 
    532 U.S. 782
    , 799
    (2001) (Penry II) (concluding that additional special instruction that allowed jury to nullify
    special issues if it concluded that other mitigating circumstances existed was constitutionally
    infirm because it “made the jury charge as a whole internally contradictory”); Tennard v.
    Dretke, 
    542 U.S. 274
    , 284 (2004) (rejecting a heightened-relevance standard applied by the
    Fifth Circuit that “has no foundation in the decisions of this Court”); Smith v. Texas, 
    543 U.S. 37
    (2004) (per curiam) (holding that the special issues in combination with general nullification
    instruction did not allow the jury to give meaningful consideration and effect to mitigating
    evidence of learning disability, low IQ score, childhood abuse, and troubled upbringing).
    9
    No. 08-70042
    respectively, and Abdul–Kabir indicates that the same clearly established law
    existed as early as 1990. 
    Abdul–Kabir, 550 U.S. at 238
    ; 
    Brewer, 550 U.S. at 294
    –95. Abdul–Kabir instructs that the relevant state-court judgment for
    purposes of review under AEDPA is the judgment adjudicating the merits of the
    petitioner’s state habeas 
    application. 550 U.S. at 238
    . The TCCA rejected
    Pierce’s petition for habeas relief in 2001. Therefore, the “clearly established
    law” described in Abdul–Kabir and Brewer controls this case.
    This circuit has construed Abdul–Kabir and Brewer as imposing a two-part
    test to determine whether resentencing is required: First, the reviewing court
    must determine whether the mitigating evidence presented by the petitioner
    satisfies the “‘low threshold for relevance’ articulated by the Supreme Court.”
    Coble v. Quarterman, 
    496 F.3d 430
    , 444 (5th Cir. 2007).5 If the relevance
    threshold is met, the court must determine “whether there was a reasonable
    likelihood that the jury applied the special issues in a manner that precluded it
    5
    The Court set out the threshold for relevance in Tennard v. Dretke, 
    542 U.S. 274
    (2004), commenting:
    [T]he meaning of relevance is no different in the context of mitigating evidence
    introduced in a capital sentencing proceeding than in any other context, and
    thus the general evidentiary standard—any tendency to make the existence of
    any fact that is of consequence to the determination of the action more probable
    or less probable than it would be without the evidence—applies. . . .
    Once this low threshold for relevance is met, the Eighth Amendment requires
    that the jury be able to consider and give effect to a capital defendant’s
    mitigating evidence.
    
    Id. at 284–85
    (internal quotation marks omitted). The Brewer majority emphasized that the
    focus of the relevance inquiry is not on the “quantity, degree, or immutability” of the
    mitigating evidence offered, but rather on whether the evidence, whatever it is, “has mitigating
    relevance to the special issues” and “may diminish a defendant’s moral culpability for the
    crime.” 
    Brewer, 550 U.S. at 294
    . A footnote of dicta in Abdul–Kabir, however, suggests an
    important limitation, stating that no special instruction is required when the “mitigating
    evidence has only a tenuous connection—some arguable relevance—to the defendant’s moral
    culpability.” 
    Abdul–Kabir, 550 U.S. at 254
    n.14 (internal quotation marks omitted). An
    additional special instruction is necessary only “when the defendant’s evidence may have
    meaningful relevance to the defendant’s moral culpability beyond the scope of the special
    issues.” 
    Id. (emphasis added;
    internal quotation marks omitted).

    No. 08-70042
    from giving meaningful consideration and effect to all of [the petitioner’s]
    mitigating evidence.”         
    Id. Both Abdul–Kabir
    and Brewer emphasize “the
    importance of allowing juries to give meaningful effect to any mitigating
    evidence providing a basis for a sentence of life rather than death.”
    
    Abdul–Kabir, 550 U.S. at 260
    (emphasis added); accord 
    Brewer, 550 U.S. at 296
    (“[T]he jury must be allowed not only to consider such evidence, or to have such
    evidence before it, but to respond to it in a reasoned, moral manner and to weigh
    such evidence in its calculus of deciding whether a defendant is truly deserving
    of death.”).6 In particular, the Texas special issues will be constitutionally
    insufficient as applied when the mitigating evidence presented supports an
    “entirely different reason for not imposing a death sentence” than permitted by
    the special issues. 
    Abdul–Kabir, 550 U.S. at 259
    . Abdul–Kabir and Brewer also
    indicate that courts should consider whether the prosecutor’s comments to the
    jury may have “undermined” the jury’s ability to give meaningful consideration
    and effect to all of the petitioner’s mitigating evidence by suggesting that the
    jurors may not consider mitigating evidence for relevance outside the special
    issues. 
    Abdul–Kabir, 550 U.S. at 261
    ; 
    Brewer, 550 U.S. at 291
    .
    2.      Franklin and Penry
    6
    Before Abdul–Kabir and Brewer, this circuit characterized the standard as requiring
    that the jury be able to “fully consider[ ] and giv[e] full effect to all of the defendant’s
    mitigating evidence.” Nelson v. Quarterman, 
    472 F.3d 287
    , 293 (5th Cir. 2006) (en banc)
    (citing 
    Tennard, 542 U.S. at 288
    –89). Since Abdul–Kabir and Brewer, this circuit has
    concluded that the “meaningful effect” and “full consideration and effect” standards are the
    same. See 
    Coble, 496 F.3d at 447
    n.15 (rejecting the State’s assertion that the “meaningful
    effect” standard was less stringent; holding that “[r]egardless of the descriptor attached to it,
    the substance of the standard articulated . . . is the same”). This conclusion finds support in
    Brewer, where the Court criticized this circuit for applying a “sufficient effect” test rather than
    a “full effect” test in evaluating Brewer’s habeas 
    petition. 550 U.S. at 295
    . Both parties cite
    the “full consideration and effect” formulation from Nelson rather than the “meaningful effect”
    formulation from Abdul–Kabir and Brewer. Because this circuit has concluded that the
    standards are identical, see 
    Coble, 496 F.3d at 447
    n.15, we cite the Supreme Court’s
    “meaningful effect” formulation.
    11
    No. 08-70042
    The standard embraced by the Court in Abdul–Kabir and Brewer was first
    articulated by Justice O’Connor in her concurrence to Franklin, 
    487 U.S. 164
    .
    In Franklin, the petitioner presented evidence at sentencing that he had
    behaved well in prison. 
    Id. at 177.
    The plurality opinion concluded that the
    future dangerousness special issue provided a sufficient vehicle for the jury to
    consider the mitigating evidence. 
    Id. at 179–80.
    The plurality rejected the
    petitioner’s contention that an additional instruction was required because the
    mitigating evidence of good behavior in prison had relevance beyond the scope
    of the special issues. 
    Id. at 181.
    The plurality reasoned that “we have never
    concluded that States cannot channel jury discretion in capital sentencing” and
    rejected the argument that the jury must be able to consider mitigating evidence
    for every issue to which it may be relevant. 
    Id. Justice O’Connor
    concurred with the plurality that the special issues were
    constitutionally sufficient as applied because the “petitioner did not suggest that
    his lack of disciplinary violations [in prison] revealed anything more positive
    about his character” than lack of future dangerousness. 
    Id. at 186
    (O’Connor,
    J., concurring). But Justice O’Connor disagreed that the special issues would be
    constitutionally sufficient if the mitigating evidence presented in fact had
    relevance beyond their scope—for example, to “personal culpability” or
    “character.” 
    Id. at 184–86.
    She commented:
    If . . . petitioner had introduced mitigating evidence about his
    background or character or the circumstances of the crime that was
    not relevant to the special verdict questions, or that had relevance
    to the defendant’s moral culpability beyond the scope of the special
    verdict questions, the jury instructions would have provided the jury
    with no vehicle for expressing its “reasoned moral response” to that
    evidence. . . . In my view, however, this is not such a case. The only
    mitigating evidence introduced by petitioner was the stipulation
    that he had no record of disciplinary violations while in prison. . . .
    While it is true that the jury was prevented from giving mitigating
    effect to the stipulation to the extent that it demonstrated positive
    12
    No. 08-70042
    character traits other than the ability to exist in prison without
    endangering jailers or fellow inmates, that limitation has no
    practical or constitutional significance in my view because the
    stipulation has no relevance to any other aspect of petitioner’s
    character. . . .
    The limited probative value of the stipulation regarding
    petitioner’s lack of prison disciplinary violations is best illustrated
    by the contrasting examples of probative character evidence
    suggested by the dissent. . . . Evidence of voluntary service,
    kindness to others, or of religious devotion might demonstrate
    positive character traits that might mitigate against the death
    penalty. Although petitioner argued to the sentencing jury that his
    prison record demonstrated his lack of future dangerousness,
    petitioner did not suggest that his lack of disciplinary violations
    revealed anything more positive about his character than that.
    
    Id. at 185–86.
          The Court adopted Justice O’Connor’s Franklin concurrence in Penry, 
    492 U.S. 302
    , in an opinion which Justice O’Connor also wrote. There, the majority
    concluded that although the deliberateness and future dangerousness special
    issues allowed the jury to give partial consideration to the petitioner’s mitigating
    evidence of mental retardation and childhood abuse, the Eighth Amendment was
    not satisfied because the mitigating evidence had “relevance to his moral
    culpability beyond the scope of the special issues, and . . . the jury was unable
    to express its ‘reasoned moral response’ to that evidence in determining whether
    death was the appropriate punishment.” 
    Id. at 322.
    D.    Analysis
    The parties do not dispute that the mitigating evidence that Pierce
    presented at his sentencing satisfies the “low threshold for relevance articulated
    by the Supreme Court.” 
    Coble, 496 F.3d at 444
    (internal quotation marks
    omitted). Instead, the parties dispute whether the Texas special issues provided
    the jury with a basis to give meaningful consideration and effect to the
    mitigating evidence that Pierce presented. The State contends that the Supreme
    13
    No. 08-70042
    Court has already ruled, over a series of cases, that the special issues provide
    jurors with a meaningful basis to consider all of the types of mitigating evidence
    that Pierce presented at sentencing. The State urges that under the Penry line,
    the special issues are only inadequate “where the defendant offers evidence of
    mental retardation or mental defect or childhood abuse or, perhaps, [childhood]
    hardship”—types of evidence that the State contends Pierce did not present in
    this case. Pierce counters that the Supreme Court has never taken a categorical
    approach to determining whether the special issues provide a basis for giving
    meaningful consideration and effect to various types of mitigating evidence, and
    he argues that the special issues did not provide such a basis in this case. Pierce
    also urges that the prosecutor’s comments to the jury during voir dire and at
    closing—which downplayed the mitigating effects of Pierce’s youth and
    suggested that the jury lacked discretion to consider mitigating evidence outside
    the confines of the special issues—further deprived the jury of a basis for
    meaningful consideration of Pierce’s mitigating evidence.
    The first issue is whether the special issues provided a basis for the jury
    to give meaningful consideration and effect to each type of mitigating evidence
    that Pierce introduced. The second issue is whether there is a reasonable
    probability that the prosecution’s voir dire questioning or closing arguments
    operated to undermine the jury’s ability to give such consideration. Pierce’s
    mitigating evidence falls into the following general categories: youth at the time
    the crime was committed, good behavior in prison, troubled childhood, and good
    character. We address these categories of mitigating evidence, and the possible
    effects of the prosecutor’s comments to the jury, in turn.
    1.    Youth and Good Behavior in Prison
    As the district court recognized, under clearly established federal law, the
    future dangerousness special issue provided a meaningful basis for the jury to
    consider and give effect to Pierce’s youth—he had just turned 18 at the time of
    14
    No. 08-70042
    the killing—and his good behavior in prison. In Johnson v. 
    Texas, 509 U.S. at 369
    , the Court held that the future dangerousness special issue gave the jury “a
    meaningful basis to consider the relevant mitigating qualities of petitioner’s
    youth,” reasoning that
    the signature qualities of youth are transient; as individuals
    mature, the impetuousness and recklessness that may dominate in
    younger years can subside. . . . [T]here is ample room in the
    assessment of future dangerousness for a juror to take account of
    the difficulties of youth as a mitigating force in the sentencing
    determination.
    
    Id. at 368.
       The Abdul–Kabir majority reiterated that youth “has special
    relevance to the question of future dangerousness” because it is “a universally
    applicable mitigating circumstance that every juror has experienced and which
    necessarily is 
    transient.” 550 U.S. at 261
    .     The Franklin plurality and
    concurrence (a total of five Justices) agreed that the future dangerousness
    special issue also allows the jury to give meaningful consideration and effect to
    a petitioner’s good behavior in 
    prison. 487 U.S. at 177
    –78, 185–86. The Court
    has not overruled this precedent. See Garcia v. Quarterman, 257 F. App’x 717,
    722 (5th Cir. 2007) (per curiam) (applying Franklin to reject the petitioner’s
    Penry claim premised on mitigating evidence of good behavior in prison). The
    special issues provided a basis for the jury to give meaningful consideration and
    effect to the mitigating evidence of Pierce’s youth and good behavior in prison.
    2.      Troubled Childhood
    Pierce also urges as mitigating evidence his mother’s testimony that he
    was a good boy until falling in with the wrong crowd when he was thirteen or
    fourteen years old, and that he spent much of his young life “locked up” during
    two extended stays in juvenile detention at the TYC. Pierce argues that this is
    evidence of a “troubled childhood”—evidence of a type that the Court held in
    Abdul–Kabir and Brewer has mitigating relevance beyond the special issues
    15
    No. 08-70042
    because it bears on a defendant’s moral culpability. See 
    Abdul–Kabir, 550 U.S. at 256
    –57 (noting that evidence of a “rough childhood” has “mitigating force
    beyond the scope of the special issues”); 
    Brewer, 550 U.S. at 293
    –94 (finding a
    Penry violation because focus on special issues would “necessarily disregard[ ]
    any independent concern that, given Brewer’s troubled background, he may not
    be deserving of a death sentence”). The State counters that Pierce’s evidence is
    different in kind than the “troubled childhood” evidence at issue in those cases
    because   those   cases   involved   circumstances   outside   the   petitioner’s
    control—such as poverty and childhood abuse—while Pierce’s evidence is limited
    to “his self-inflicted problems with the law.”
    The case law does not support the distinction that the State urges. In
    Brewer, for example, the Court concluded that an additional instruction was
    necessary in order to allow the jury to consider and give effect to evidence that
    the petitioner’s “co-defendant, a woman with whom he was apparently obsessed,
    dominated and manipulated him,” and that the petitioner had a history of
    substance 
    abuse. 550 U.S. at 289
    –90 (internal quotation marks omitted). The
    Brewer majority concluded that there was a reasonable likelihood that the
    special issues led the jury to “disregard[ ] any independent concern that, given
    Brewer’s troubled background, he may not be deserving of a death sentence,”
    and therefore deprived the jury of the opportunity to respond to the petitioner’s
    mitigating evidence in a “reasoned moral manner.” 
    Id. at 294,
    296. Similarly,
    this circuit has held that evidence of a petitioner’s substance abuse might have
    “meaningful mitigating relevance beyond its tendency to disprove that [the
    petitioner] acted deliberately” and therefore requires an additional instruction.
    Garcia, 257 F. App’x at 722 (internal quotation marks omitted). Both of these
    cases involved mitigating evidence that was arguably “self-inflicted” (to use the
    State’s term), but recognized that this evidence might nevertheless have
    mitigating relevance to the petitioner’s moral culpability—and therefore
    16
    No. 08-70042
    relevance outside the special issues. These holdings are consistent with the
    requirement that juries be allowed “to give meaningful effect to any mitigating
    evidence providing a basis for a sentence of life rather than death.”
    
    Abdul–Kabir, 550 U.S. at 260
    (emphases added).          Consistent with these
    precedents, Pierce’s evidence of being led astray by older boys and being locked
    up for a significant period of time at the TYC had mitigating relevance beyond
    the special issues and therefore required an additional instruction.
    3.    Good Character
    Pierce introduced evidence of his good character before the crime,
    including that he was kind to his mother, was honest and admitted past wrongs
    to her, and regularly attended church. Pierce also presented evidence of his good
    character as it developed after he committed the crime. This evidence included
    that he had matured emotionally and spiritually while in prison, developing his
    ability to speak and articulate his thoughts and becoming more open and able
    to communicate his feelings. Pierce also matured in prison by furthering his
    education, improving his reading skills, and developing his talent for art and
    woodworking.
    In Franklin, five Justices (two concurring, three dissenting) indicated, in
    dicta, that the special issues would not allow a jury to give meaningful
    consideration and effect to this type of “good character” evidence. Justice
    O’Connor’s concurrence stated that although the petitioner’s evidence of good
    behavior in prison lacked relevance to any issue other than future
    dangerousness, had the petitioner presented “[e]vidence of voluntary service,
    kindness to others, or of religious devotion,” an additional instruction would
    have been required:
    [i]f [the] petitioner had introduced mitigating evidence about his
    background or character or the circumstances of the crime that was
    not relevant to the special verdict questions, or that had relevance
    to the defendant’s moral culpability beyond the scope of the special
    17
    No. 08-70042
    verdict questions, the jury instructions would have provided the jury
    with no vehicle for expressing its “reasoned moral response” to that
    
    evidence. 487 U.S. at 185
    –86 (O’Connor, J., concurring). Justice Stevens’s dissent likewise
    emphasized that character evidence of this type “may suggest that the conduct
    of which the defendant stands convicted was not in keeping with his or her usual
    qualities or traits, a fact that has as much relevance to culpability as to future
    dangerousness.” 
    Id. at 190
    (Stevens, J., dissenting).
    Since Franklin, the Court’s jurisprudence on California’s death penalty
    statute7 has repeatedly held that character evidence has relevance to a
    petitioner’s moral culpability. See, e.g., Ayers v. Belmontes, 
    549 U.S. 7
    , 15 (2006)
    (noting that good character evidence may “extenuate[ ] the gravity of the crime”);
    Brown v. Payton, 
    544 U.S. 133
    , 142–43 (2005) (commenting on the relevance of
    good character evidence as a means of “lessen[ing] or excus[ing] a defendant’s
    culpability”); Boyde v. California, 
    494 U.S. 370
    , 382 n.5 (1990) (commenting on
    relevance of good character evidence as a means of showing “character strengths
    in the face of . . . difficulties” and showing that “criminal conduct was an
    aberration from otherwise good character”).8 Evidence of “postcrime character
    transformations” is also relevant:
    [T]o accept the view that such evidence could not [be relevant to
    moral culpability] because it occurred after the crime, one would
    have to reach the surprising conclusion that remorse could never
    serve to lessen or excuse a crime. But remorse, which by definition
    can only be experienced after a crime’s commission, is something
    commonly thought to lessen or excuse a defendant’s culpability.
    7
    California’s death penalty statute sets out eleven factors “that the trier of fact shall
    take into account . . . if relevant.” Relevant here is factor (k), which instructs the trier of fact
    to consider “[a]ny other circumstance which extenuates the gravity of the crime even though
    it is not a legal excuse for the crime.” CAL. PENAL CODE ANN. § 190.3(k) (West 2008).
    8
    As a direct appeal, Boyde was not governed by 
    AEDPA. 494 U.S. at 376
    .
    18
    No. 08-70042
    
    Brown, 544 U.S. at 142
    –43; see also 
    Ayers, 549 U.S. at 15
    –16 (noting that it
    would be “counterintuitive if a defendant’s capacity to redeem himself through
    good works [after the crime] could not extenuate his offense and render him less
    deserving of a death sentence”). Ayers and Brown set out the clearly established
    law as it existed in 
    1994. 549 U.S. at 10
    ; 544 U.S. at 139. Boyde was a direct
    appeal decided in 1990, well before the denial of Pierce’s state habeas application
    became final in 2001. All of these authorities set out the clearly established law
    for purposes of this case.
    The Court has addressed good character evidence in the context of the
    Texas special issues only once since Franklin, in Graham v. Collins, 
    506 U.S. 461
    . The State urges that Graham stands for the proposition that the special
    issues allow juries to give meaningful consideration and effect to good character
    evidence. In Graham, the Court considered the petitioner’s mitigating evidence
    that he had a transient upbringing, was a generous person, and “loved the Lord.”
    
    Id. at 464
    (alterations omitted). The Court stated, in dicta, that the special
    issues allowed the jury to give at least some effect to this character evidence, and
    indicated that some effect was all that was constitutionally required. 
    Id. at 476–77.
    Graham’s actual holding, however, was that under the law as it existed
    in 1984 (the year the petitioner’s conviction became final) the relief that the
    petitioner sought would have constituted a new rule, in violation of Teague v.
    Lane, 
    489 U.S. 288
    (1989). 
    Id. at 477.
    The Abdul–Kabir majority took pains to
    distinguish Graham’s “some effect” language as 
    dicta, 550 U.S. at 258
    –59, as did
    this court in Nelson, in which we rejected the State’s contention that Graham
    altered the requirement that the jury be able to give “full consideration and full
    effect to the capital defendant’s mitigating 
    evidence,” 472 F.3d at 298
    (“Because
    19
    No. 08-70042
    the [Graham] Court disposed of the case on Teague grounds, it did not address
    the substantive merits of the petitioner’s Penry claim.”).9
    Both Abdul–Kabir and Brewer emphasize “the importance of allowing
    juries to give meaningful effect to any mitigating evidence providing a basis for
    a sentence of life rather than death.” 
    Abdul–Kabir, 550 U.S. at 260
    (emphases
    added).     The California cases establish that good character evidence has
    meaningful relevance to moral culpability, which a majority of the Justices in
    Franklin indicated is not encompassed by the special issues. These authorities
    establish that an additional instruction was required in order for the jury to
    consider and give effect to this mitigating evidence.
    4.      Effect of Certain Comments to the Jury
    In Abdul–Kabir and Brewer, the Court indicated that a prosecutor’s
    comments to the jury at voir dire and at closing may further impede the ability
    of the jury to give meaningful consideration and effect to mitigating evidence.
    Pierce complains that the prosecutor, at his sentencing, impressed upon the
    jurors in closing argument that they could not consider evidence with relevance
    beyond the special issues:
    You each promised me individually that if the State brought you
    evidence that convinced you beyond a reasonable doubt that the
    answers to these special issues would be yes and you knew that a
    “yes” answer to each one of these issues would mean the death
    9
    The State cites several cases from this circuit that cite Graham for the proposition that
    “because ‘the principal mitigating thrust of good character evidence is to show that the
    defendant acted atypically in committing the capital crime, this evidence can find adequate
    expression under the second special issue.’” Bower v. Dretke, 145 F. App’x 879, 885 (5th Cir.
    2005) (per curiam) (quoting Barnard v. Collins, 
    958 F.2d 634
    , 640 (5th Cir. 1992)); see also
    Coble v. Dretke, 
    417 F.3d 508
    , 525 (5th Cir. 2005) (“‘Evidence of good character tends to show
    that the crime was an aberration, which may support a negative answer to the special issue
    regarding the future dangerousness of the defendant.’” (quoting Boyd v. Johnson, 
    167 F.3d 907
    , 912 (5th Cir. 1999))), withdrawn and superseded on rehearing, Coble v. Quarterman, 
    496 F.3d 430
    . But these cases predate Abdul–Kabir and fail to recognize that Graham’s “some
    effect” language was dicta that the Supreme Court identified as such in Abdul–Kabir and this
    court has since similarly distinguished. See 
    Nelson, 472 F.3d at 298
    , 303.
    20
    No. 08-70042
    penalty that you would answer those questions “yes” and that you
    would never change your answer despite the evidence in this case
    just so that the death penalty would not be imposed.
    As the district court observed, these comments are very similar (indeed,
    nearly identical) to those that the Court criticized in Abdul–Kabir, in which the
    prosecutor reminded jurors that they had “‘promise[d’ to] look only at the
    questions posed by the special issues, which, according to the prosecutor,
    required the jurors to put the petitioner’s mitigating evidence ‘out of [their]
    mind[s]’ and ‘just go by the 
    facts.’” 550 U.S. at 261
    . The Abdul–Kabir Court
    concluded that these comments had the effect of impermissibly “convinc[ing]
    jurors that the law compels them to disregard the force of the evidence offered
    in mitigation” that had relevance outside the special issues. 
    Id. The prosecutor’s
    closing comments in this case are also similar to those
    that the Court criticized in Brewer, where the prosecutor urged the jury that
    “‘you don’t have the power to say whether [the petitioner] lives or dies. You
    answer the questions according to the evidence, much like you did at the guilt
    or innocence [phase]. That’s all.’” 
    Brewer, 550 U.S. at 291
    (alterations omitted).
    Finding a Penry violation, the Brewer Court concluded that “[t]here [wa]s surely
    a reasonable likelihood that the jurors accepted the prosecutor’s argument at the
    close of the sentencing hearing that all they needed to decide was whether
    Brewer had acted deliberately and would likely be dangerous in the future,
    necessarily disregarding any independent concern that, given Brewer’s troubled
    background, he may not be deserving of a death sentence.” 
    Id. at 293–94
    (footnote omitted). To the extent that Pierce presented evidence that could not
    be given meaningful consideration and effect under the special issues, the
    prosecution’s closing argument may have exacerbated the problem by instructing
    the jury to consider only the special issues.
    21
    No. 08-70042
    Certain of the prosecutor’s comments at voir dire were also problematic.
    The prosecutor elicited agreement from one venire member (who was later
    selected to serve on the jury) that “under our law . . . the age of an individual . . .
    in and of itself does not give anyone special rights,” and that “whether a person
    is 17 or they’re 85, the law doesn’t ask how old you are . . . it asks that you follow
    certain norms and those norms determine the interaction between human beings
    and violation of those be tried by a jury . . . .” The prosecutor elicited agreement
    from another venire member (also selected to the jury) that “our law, as far as
    making a person guilty or being charged with capital murder—like that doesn’t
    distinguish whether or not that person happens to be 17 or 18 . . . as far as
    whether or not they violate the law” and the statement that she would not
    necessarily answer the second special issue “no” because of the defendant’s age.
    The Abdul-Kabir majority observed that comments like these, which “tak[e]
    pains to convince jurors that the law compels them to disregard the force of
    evidence offered in mitigation,” might “undermine[ ]” a jury’s ability to give
    meaningful consideration and effect even to evidence encompassed by the special
    
    issues. 550 U.S. at 261
    . By essentially instructing the venire members that
    “youth isn’t relevant,” the comments may have undermined the jury’s ability to
    give mitigating effect to evidence of Pierce’s youth through the special issues.
    E.    Conclusion
    Under the clearly established law, the special issues provided a basis for
    the jury to give meaningful consideration and effect to Pierce’s mitigating
    evidence of youth and good behavior in prison but did not provide such a basis
    for the remainder of Pierce’s mitigating evidence. The prosecutor’s closing
    comments may have exacerbated this problem by impressing upon the jury that
    its deliberations should be guided by the special issues alone. The prosecutor’s
    comments at voir dire may have also undermined the jury’s ability to give
    meaningful consideration and effect under the special issues to the evidence of
    22
    No. 08-70042
    Pierce’s youth. Accordingly, we affirm the district court’s order of resentencing.
    Because we affirm on this basis, we do not consider whether Pierce’s claim of
    ineffective assistance of counsel at sentencing provides an alternative basis for
    resentencing. Accord Beckham v. Wainwright, 
    639 F.2d 262
    , 265 n.4 (5th Cir.
    Unit B Mar. 1981) (declining to consider whether the alleged denials of the right
    to confrontation and right to jury trial provided bases for habeas relief and a new
    trial because the petitioner’s ineffective assistance claim provided such a basis).
    IV. THE ATKINS CLAIM
    We granted a COA on the issue of whether Pierce is ineligible for the death
    penalty under Atkins v. Virginia, 
    536 U.S. 304
    , in which the Supreme Court held
    that the Eighth Amendment forbids the execution of mentally retarded persons.
    The Atkins Court “le[ft] to the State[s] the task of developing appropriate ways
    to enforce the constitutional restriction upon their execution of sentences.” 
    Id. at 317
    (alterations and internal quotation marks omitted). In Texas, a finding
    of mental retardation requires:       (1) significantly sub-average intellectual
    functioning (generally, an IQ of 70 or below); (2) deficits in adaptive functioning;
    and (3) onset before age 18. See Ex parte Briseno, 
    135 S.W.3d 1
    , 7 (Tex. Crim.
    App. 2004). Pierce bore the burden of establishing by a preponderance of the
    evidence that he is mentally retarded. 
    Id. at 7–8,
    12; Woods v. Quarterman, 
    493 F.3d 580
    , 585 & n.3 (5th Cir. 2007). Pierce contends that the district court erred
    in concluding that the state habeas court was not unreasonable in determining
    that Pierce does not meet the Texas definition of a mentally retarded person.
    A.    Background
    We briefly summarize the evidence that the state habeas court considered
    as to Pierce’s Atkins claim in order to provide a background for our analysis of
    Pierce’s contentions. Dr. George Denkowski submitted an affidavit for the State.
    Dr. Denkowski reviewed documents and examined Pierce in prison,
    administering, among other tests, the Stanford–Binet Intelligence Scales—Fifth
    23
    No. 08-70042
    Edition (SB-5) and the Adaptive Behavior Assessment System (ABAS). Pierce
    attained a full-scale IQ score of 80 on Dr. Denkowski’s administration of the SB-
    5. Dr. Denkowski opined that Pierce’s IQ might actually be slightly higher than
    this score suggested because Pierce suffered from moderate anxiety and mild
    depression, which may have suppressed the score. Pierce’s ABAS results showed
    a significant adaptive deficit only in functional academics.
    Three expert witnesses submitted affidavits on Pierce’s behalf. The first
    expert, Dr. June Kaufman, examined and evaluated Pierce in connection with
    his original state habeas application in 1990. Dr. Kaufman’s affidavit did not
    include an IQ score for Pierce, but did opine that he was “functionally mentally
    retarded” and displayed adaptive deficits in the form of “understand[ing]
    society’s basic value systems and conventions,” which resulted in “extremely
    poor social judgment in everyday life situations.” The second expert, Dr. Richard
    Garnett, did not examine Pierce but did review his records. Dr. Garnett noted
    that Pierce had attained IQ scores ranging from 67 to 81 on various tests
    administered during his childhood and young adulthood and observed that
    Pierce appeared to perform best in structured settings, a trait common among
    the mentally retarded. The third expert, Dr. Susana Rosin, administered the
    Wechsler Adult Intelligence Scale III, on which Pierce attained an IQ score of 70.
    Dr. Denkowski’s affidavit questioned that score, arguing that the result was
    unreliable because Dr. Rosin had administered only a short form of that test.
    Dr. Rosin also completed the Vineland Adaptive Behavior Scales using
    information from Pierce’s records, reports from the Assistant Warden on death
    row, and information provided by Pierce. Dr. Rosin’s Vineland results showed
    a significant adaptive deficit only in communication.
    The State habeas trial court considered these affidavits and adopted the
    proposed findings of fact and conclusions of law submitted by the State. These
    included that the contents of Dr. Denkowski’s affidavit—including his various
    24
    No. 08-70042
    criticisms of Pierce’s experts’ affidavit testimony—were credible. These also
    included that because Dr. Garnett was not certified by the Texas Department of
    Mental Health and Mental Retardation to make a diagnosis of mental
    retardation but was instead a licensed marriage and family counselor, he was
    not qualified to make a diagnosis of mental retardation under Texas law. The
    TCCA rejected the state habeas trial court’s finding as to Dr. Garnett’s
    qualification to diagnose mental retardation, but otherwise adopted the state
    habeas trial court’s findings of fact and conclusions of law.
    In support of his claim for federal habeas relief, Pierce sought an
    evidentiary hearing in the federal district court as to whether he is mentally
    retarded. Pierce urged in the district court, and continues to urge in this court,
    that a hearing is warranted because there is “new evidence” that Dr. Denkowski
    was discredited by the TCCA in another death penalty case after making several
    methodological errors. See Ex parte Plata, No. AP-75820, 
    2008 WL 151296
    (Tex.
    Crim. App. Jan. 16, 2008) (per curiam). Pierce contends that Dr. Denkowski
    committed some of those same errors in the present case and also points to
    additional purported shortcomings in Dr. Denkowski’s analysis that did not
    occur in Plata. Pierce also asserts, for the first time on appeal, that the state
    habeas trial court erroneously found that Dr. Garnett was not qualified to
    diagnose mental retardation, and that although the TCCA declined to adopt this
    finding, other of the findings that the TCCA did adopt were premised upon this
    finding.
    The district court declined to hold an evidentiary hearing on the putative
    new evidence and concluded that all of the errors that Dr. Denkowski
    purportedly committed in Plata either were not committed in Pierce’s case or
    would not have affected the state habeas court’s conclusions. Pierce, 
    2008 WL 4445064
    , at **13–15. Pierce asks this court to conclude that the district court
    abused its discretion in refusing to hold an evidentiary hearing.          In the
    25
    No. 08-70042
    alternative, Pierce asks, for the first time on appeal, that this court stay the case
    and hold it in abeyance while the state habeas court (to which he proposes to
    repair) considers the “new evidence” as to Dr. Denkowski’s performance in Plata.
    B. Atkins Issues Raised in the COA Application
    Pierce’s COA application raised the following five specific issues as bases
    for relief under Atkins:
    1.    As in Plata, Dr. Denkowski improperly contended that depression and
    anxiety had a suppressive effect on Pierce’s IQ score;
    2.    As in Plata, Dr. Denkowski improperly evaluated Pierce’s adaptive deficits
    and overstated the impact of sociocultural factors on these deficits;
    3.    Dr. Denkowski improperly criticized the results of IQ tests administered
    to Pierce by other experts as being less reliable because only certain
    subparts were administered;
    4.    Dr. Denkowski failed to inform the court of the “Flynn Effect,” which
    might have artificially inflated Pierce’s IQ score on tests administered by
    other experts in 1975 and 1976. Dr. Denkowski also failed to inform the
    court that these same tests may be structured so as to overrepresent IQ;
    and
    5.    The state habeas trial court made a clearly erroneous finding of fact that
    one of Pierce’s experts, Dr. Garnett, was not qualified to diagnose mental
    retardation. Although the TCCA declined to adopt this finding of fact, the
    state habeas trial court’s other findings of fact as to Dr. Garnett, which the
    TCCA did adopt, improperly relied on this erroneous finding.
    In granting a COA, we directed Pierce to “provide a record citation to
    where each such issue was raised before the state habeas court and federal
    district court—or, if the issue was not raised in these forums, to explain why the
    issue could not have been raised there.”
    C.    Analysis
    For the first two issues on which we granted a COA, Pierce contends that,
    as in Plata, Dr. Denkowski improperly testified that depression and anxiety had
    a depressive effect on Pierce’s IQ score and improperly evaluated Pierce’s
    26
    No. 08-70042
    adaptive deficits, overstating the impact of sociocultural factors on these deficits.
    But the district court addressed both of these arguments. As to Pierce’s IQ
    score, the district court observed that in Pierce’s case, unlike in Plata, “Dr.
    Denkowski did not have to rely on claims of clinical judgment to achieve an IQ
    score that is above the mentally retarded range.” Pierce, 
    2008 WL 4445064
    , at
    *13. Pierce attained a full-scale IQ of 80 on Dr. Denkowski’s administration of
    the SB-5 before making any adjustments for depression or anxiety. 
    Id. As to
    Pierce’s adaptive deficits, the district court held that even if Dr. Denkowski’s
    evidence were not considered, “the evidence supports a finding that Pierce does
    not have significant deficits in adaptive behavior.” 
    Id. at *15.
    Pierce’s COA
    application and supplemental briefing do not actually challenge the district
    court’s conclusions as to these issues. These issues, therefore, do not provide a
    basis for Atkins relief.10 See Ortiz v. Quarterman, 
    504 F.3d 492
    , 501 n.6 (5th Cir.
    2007); Hughes v. Johnson, 
    191 F.3d 607
    , 613 (5th Cir. 1999).
    As to the third and fourth issues on which we granted a COA—that Dr.
    Denkowski improperly criticized the reliability of Pierce’s short-form IQ test
    scores and failed to explain how the “Flynn Effect” and structural test flaws
    would have inflated the results of tests that other specialists administered to
    Pierce—Pierce concedes that he never raised these issues before the district
    court. Pierce contends that he did not do so because his strategy before the
    district court was to argue “that Denkowski’s credibility had been globally
    undermined by Plata and that an evidentiary hearing was required to determine
    precisely how Denkowski applied similarly flawed methodologies in this case.”
    10
    In any event, to the extent that Dr. Denkowski might have committed these errors
    in Pierce’s case, the fact of these errors would not be “new evidence” in light of Plata because
    these errors were factual in nature and could have been identified by Pierce’s experts before
    Plata was published. Pierce submitted the affidavit testimony of three expert witnesses on
    mental retardation in connection with his state habeas application and federal habeas petition.
    None of these affidavits cited any errors in Dr. Denkowski’s affidavit.
    27
    No. 08-70042
    Pierce argues that the “gist” of his argument in the district court was that Dr.
    Denkowski’s entire opinion was infected with errors, and that he raised these
    discrete issues on appeal simply to highlight examples: “These arguments were
    intended to highlight significant flaws in Denkowski’s methodologies . . . and to
    show that it is simply not possible to carve out the flawed portions of
    Denkowski’s report and then make a determination that what remains is
    scientifically sound and supports the state court’s decision.”
    Pierce’s argument is not persuasive and does not provide a basis for
    granting habeas relief or an evidentiary hearing. First, Pierce admits that he
    did not raise these contentions in the district court. “‘[W]e have repeatedly held
    that a contention not raised by a habeas petitioner in the district court cannot
    be considered for the first time on appeal from that court’s denial of habeas
    relief.’” Goodrum v. Quarterman, 
    547 F.3d 249
    , 259 n.49 (5th Cir. 2008) (quoting
    Johnson v. Puckett, 
    930 F.2d 445
    , 448 (5th Cir. 1991)). Second, contrary to
    Pierce’s assertions about his “global” strategy in the district court, Pierce did in
    fact argue in the district court that Dr. Denkowski’s affidavit contained a
    number of specific errors—but those alleged errors were different than those
    that he now urges on appeal. Third, none of Pierce’s own experts raised the
    “Flynn Effect” or structural test flaws as reasons for concluding that Pierce’s IQ
    was lower than his scores on IQ tests not administered by Dr. Denkowski might
    indicate. Finally, neither the accuracy of short-form test scores, nor the “Flynn
    Effect,” nor alleged structural test flaws were at issue in Plata. In short, Pierce’s
    argument that Dr. Denkowski’s work in Plata provides “new evidence” that Dr.
    Denkowski performed deficiently has no merit and does not provide a basis for
    habeas relief or an evidentiary hearing.11 Because Pierce’s contentions as to
    11
    Pierce seems to suggest that errors in an expert witness’s work in another case,
    without a showing that those errors occurred in or may have affected the outcome of the
    petitioner’s case, can provide a proper basis for habeas relief or an evidentiary hearing. Pierce
    cites no authority for this proposition, and we have located none. In evaluating Pierce’s
    28
    No. 08-70042
    “new evidence” lack merit, we also deny Pierce’s request, raised for the first time
    on appeal, to stay the case and hold it in abeyance while the state habeas court
    considers the “new evidence” as to Dr. Denkowski’s performance in Plata.
    As to the fifth issue on which we granted a COA—whether the state
    habeas court’s finding that Dr. Garnett was not qualified to diagnose mental
    retardation, which the TCCA rejected, improperly affected other findings of fact
    about Dr. Garnett that the TCCA adopted—Pierce again admits that he did not
    raise this issue before the district court. It therefore does not provide a basis for
    relief. See 
    Goodrum, 547 F.3d at 259
    n.49; 
    Puckett, 930 F.2d at 448
    . In any
    event, the TCCA’s order reveals no evidence of any such taint. The TCCA
    adopted the following factual findings: Dr. Garnett did not examine Pierce but
    merely reviewed his records; Dr. Garnett is not licensed as a psychologist in the
    state of Texas but instead is a licensed marriage and family counselor; in other
    cases, Dr. Garnett has been found to be biased or inexperienced; and based on
    other evidence in the record as to Pierce’s mental faculties, Dr. Garnett’s
    diagnosis of mental retardation was “unpersuasive.” None of these findings
    relies on the trial court’s erroneous finding, rejected by the TCCA, that Dr.
    Garnett was unqualified to diagnose an individual as mentally retarded. There
    is no basis in the record to conclude that the TCCA’s findings were in any way
    dependent on the finding of fact that the TCCA rejected.
    None of the issues raised in Pierce’s habeas application provides a basis
    for habeas relief or an evidentiary hearing. Accordingly, we affirm the district
    court’s denial of Atkins relief.
    D.     The Dissent’s Argument for an Evidentiary Hearing
    application for habeas relief, the district court’s task was to determine whether the state
    habeas court’s determination of the facts was reasonable and whether the “new evidence” of
    Dr. Denkowski’s performance in Plata called that determination into question. The district
    court concluded that the errors in Plata that Pierce contended Dr. Denkowski also made in his
    own case either did not occur or would not have affected the result.
    29
    No. 08-70042
    The dissent argues that Pierce is entitled to an evidentiary hearing in the
    federal district court on his Atkins claim because the state habeas court did not
    hold a live evidentiary hearing to determine whether Pierce was mentally
    retarded. The dissent urges this court to conclude that, as a matter of clearly
    established Supreme Court law, a live evidentiary hearing is “guaranteed to a
    prisoner who has made a plausible showing of mental retardation.”
    The most critical obstacle to the relief the dissent proposes is that Pierce
    never, in either his pleadings or voluminous briefing, cited the lack of a live
    evidentiary hearing in the state habeas court as a basis for obtaining an
    evidentiary hearing in the federal district court.12 Throughout his federal
    habeas proceedings, Pierce’s request for an evidentiary hearing has been
    premised solely on the propositions—which this entire panel has rejected—that
    Plata provided “new evidence” that Dr. Denkowski’s affidavit testimony to the
    state habeas court was unreliable and that the TCCA may have adopted
    erroneous findings of fact regarding Dr. Garnett. Under our precedents, because
    Pierce did not raise the lack of an evidentiary hearing in the state court as a
    basis for relief in the district court or even in his pleadings and briefing to this
    court, we cannot consider it here. See 
    Goodrum, 547 F.3d at 259
    n.49; 
    Puckett, 930 F.2d at 448
    .
    V. CONCLUSION
    We AFFIRM the district court’s grant of habeas relief based on the Penry
    violations at Pierce’s sentencing, and accordingly AFFIRM the district court’s
    resentencing order. Because we affirm resentencing on this basis, we do not
    address whether Pierce’s ineffective assistance of counsel claim provides an
    12
    Pierce did not make an effort to develop this argument even when the dissent to our
    denial of a COA specifically invited him to do so—rather, in his supplemental briefing, Pierce
    stated only that he “would add the concerns discussed by Justice Dennis in his concurring and
    dissenting opinion in this case as additional reasons why a hearing is required in this case.”
    30
    No. 08-70042
    additional basis for resentencing. We AFFIRM the district court’s denial of
    habeas relief and an evidentiary hearing on Pierce’s Atkins claim.
    AFFIRMED.
    31
    No. 08-70042
    DENNIS, Circuit Judge, concurring in part and dissenting in part:
    I respectfully dissent from the majority’s reasons and conclusion in
    rejecting Pierce’s Atkins claim, because the procedure the Texas courts used to
    determine whether Pierce is mentally retarded did not comply with the
    requirements of constitutional due process. In all other respects consistent with
    this view, I concur in the majority opinion.
    I.
    Pierce was found not to be mentally retarded by a state habeas court
    judge on the basis of an affidavit by the state’s expert, without a live adversarial
    evidentiary hearing, without an opportunity to testify or call witnesses, and
    without an opportunity to confront and cross-examine the witness against him.
    In the state habeas proceedings, Pierce presented the affidavits of three mental
    retardation experts, Dr. June Kaufman, Dr. Richard Garnett, and Dr. Susana
    Rosin, who each set forth his or her findings, evaluation and opinion that Pierce
    is mentally retarded.1 The state presented the affidavit of its expert, Dr. George
    1
    Dr. Kaufman, a clinical psychologist, evaluated Pierce in 1990. She administered the
    Wechsler Adult Intelligence Scale-Revised, the result of which she considered “without
    question valid.” Dr. Kaufman also noted that Pierce exhibited classic traits of the mentally
    retarded and pointed to Pierce’s adaptive behavioral issues, observing that he did not think
    through the consequences of his actions, had gross deficiencies comprehending society’s basic
    value systems and conventions and exhibited extremely poor social judgment in everyday life
    situations. Against this background and his earlier IQ scores of 74 in 1972 and 1974 and 67
    in 1975, Dr. Kaufman concluded that Pierce was mentally retarded at the time of the crime
    in 1977.
    Dr. Garnett submitted an affidavit in support of Pierce’s successive state habeas
    petition in 2002. Dr. Garnett also opined that Pierce was mentally retarded. He noted that
    Pierce scored below 75 on seven IQ tests over a period of several years, and that a test score
    of 81 on the Wechsler Adult Intelligence Scale in 1976 was an outlier and may have had to do
    with hints from the administrator or the test-retest factor. Further, Dr. Garnett also noted
    that Pierce had significant adaptive deficits. He pointed out that it was common for a mentally
    retarded person to respond well to structured settings, such as a prison, as is the case with
    Pierce, only to revert back to unacceptable or illegal behavior as soon as he is outside of that
    environment.
    Dr. Rosin, a clinical psychologist, evaluated Pierce in support of his state habeas
    application in 2002. She noted that Pierce’s school records showed a consistent pattern of
    underachievement and observed that Pierce obtained full scale IQ scores of 69 at age nine and
    74 at age twelve, both on the Otis-Lennon Test of Mental Ability, and two scores of 67 and 75
    on tests administered in 1975. Dr. Rosin administered the Wechsler Adult Intelligence
    Scale-III, on which Pierce scored an IQ of 70. Dr. Rosin further noted that Pierce had
    No. 08-70042
    Denkowski, which set forth his evaluation and opinion that Pierce is not
    mentally retarded. Dr. Denkowski’s affidavit also contained his reasons for
    discounting or disagreeing with the contrary opinions of Pierce’s experts.2 Pierce
    requested a contradictory evidentiary hearing. But the state habeas court
    denied Pierce’s motion and did not seek any further input from Pierce’s experts.
    Rather, the state court found that Dr. Denkowski presented a “credible affidavit”
    and, on the basis of that affidavit, decided that Pierce is not mentally retarded.3
    Accordingly, the state habeas trial court held that Pierce is not exempt from the
    significant deficits in conceptual, social and practical skills, pointing to his long history of
    problems socializing with others, exercising sound judgment, resisting peer pressure, and
    learning from past experiences. According to Dr. Rosin, his IQ score and his adaptive deficits
    placed him in the mildly mentally retarded range.
    2
    Dr. Denkowski reviewed Pierce’s files and evaluated him on death row. He
    administered the Stanford-Binet Intelligence Scales-Fifth Edition, on which he said Pierce
    achieved a score of 80. Dr. Denkowski opined that, adjusted for moderate anxiety and mild
    depression, his score was actually in the 80 to 84 range. Further, Dr. Denkowski opined that,
    apart from his low academic skills, Pierce did not have significant deficits in adaptive
    functioning. Dr. Denkowski’s affidavit otherwise focused on criticizing the opinions of Pierce’s
    three experts–shielded from any form of response or cross examination.
    3
    The state habeas court completely ignored that the expert witnesses examined Pierce
    at wide intervals (in one instance over a decade apart) and under differing circumstances, with
    some having analyzed Pierce and made findings prior to the Supreme Court’s decision in
    Atkins; a wide variety of tests were administered involving varying parameters and substantial
    nuance and complexity; and the mental health experts sharply disagreed on whether Pierce
    is mentally retarded and submitted diametrically opposed affidavits. Additionally, the
    qualifications and integrity of Dr. Denkowski, whose affidavit was the pivotal and exclusive
    basis for the state trial habeas court’s finding that Pierce was not mentally retarded, are now
    under close scrutiny and his methods have been recognized to be unreliable by this court, the
    Texas state courts, and the state licensing authorities. See Hall v. Quarterman, 
    534 F.3d 365
    ,
    371 n.27 (5th Cir. 2008); 
    id. at 376
    (Higginbotham, J., concurring in part and dissenting in
    part); Ex parte Plata, No. 693143-B (351st Dist. Ct. Sept. 28, 2007), aff’d, No. AP-75820, 
    2008 WL 151296
    (Tex. Crim. App. Jan. 16, 2008); Tex. State Bd. of Examiners of Psychologists v.

    death penalty. On appeal, the TCCA adopted the state habeas trial court’s
    findings and conclusions.4
    The federal district habeas court refused to grant Pierce an evidentiary
    hearing on his Atkins claim, found that the state courts’ rejection of his Atkins
    claim was not unreasonable under AEDPA, and therefore rejected his petition
    for federal habeas relief. Pierce v. Quarterman, No. H-07-1561, 
    2008 WL 4445064
    , at **13-15 (S.D. Tex. Sept. 26, 2008). In doing so, the district court
    failed to enforce Pierce’s clearly established constitutional right to procedural
    due process.
    II.
    Construing and applying the Eighth Amendment in the light of our
    “evolving standards of decency,” the Supreme Court in Atkins v. Virginia, 
    536 U.S. 304
    , 321 (2002), held that the Constitution “‘places a substantive restriction
    on the State’s power to take the life’ of a mentally retarded offender.” 
    Id. (quoting Ford
    v. Wainwright, 
    477 U.S. 399
    , 405 (1986)). In Schriro v. Smith, the
    Court observed that Atkins stated in clear terms that “‘we leave to the State[s]
    the task of developing appropriate ways to enforce the constitutional restriction
    upon [their] execution of sentences,’” 
    546 U.S. 6
    , 7 (2005) (alterations in original)
    (quoting 
    Atkins, 536 U.S. at 317
    ), but also stated that “those measures might,
    in their application, be subject to constitutional challenge,” 
    id. Thus, under
    Atkins a person has a substantive right not to be executed if he is mentally
    retarded, and once he makes a prima facie showing that he is mentally retarded,
    4
    The only state habeas trial court finding not adopted by the TCCA was its clearly
    erroneous exclusion of Dr. Garnett’s affidavit on the basis that he was not licensed in Texas
    and thus ineligible to opine on mental retardation in civil commitments under the Persons with
    Mental Retardation Act, Tex. Health & Safety Code § 591.003(16).

    he is entitled to an adjudication meeting constitutional standards to determine
    his condition.5
    “The Fourteenth Amendment’s Due Process Clause protects persons
    against deprivations of life, liberty, or property; and those who seek to invoke its
    procedural protection must establish that one of these interests is at stake.”
    Wilkinson v. Austin, 
    545 U.S. 209
    , 221 (2005). “A liberty interest may arise from
    the Constitution itself, by reason of guarantees implicit in the word ‘liberty,’ or
    it may arise from an expectation or interest created by state laws or policies.”
    
    Id. (citing Vitek
    v. Jones, 
    445 U.S. 480
    , 493-494 (1980) (liberty interest in
    avoiding involuntary psychiatric treatment and transfer to mental institution)
    & Wolff v. McDonnell, 
    418 U.S. 539
    , 556-558 (1974) (liberty interest in avoiding
    withdrawal of state-created system of good-time credits)).
    In Vitek, the Court held that, “[b]ecause prisoners facing involuntary
    transfer to a mental hospital are threatened with immediate deprivation of
    liberty interests and because of the inherent risk of a mistaken transfer,” due
    process requires procedures similar to those required in parole revocation
    proceedings. 
    Id. at 495-96
    (citing Morrissey v. Brewer, 
    408 U.S. 471
    (1972)).
    According to Vitek, the minimum procedures before transferring a prisoner to a
    mental hospital include the following: (1) “Written notice to the prisoner that a
    transfer to a mental hospital is being considered”; (2) “A hearing, sufficiently
    after the notice to permit the prisoner to prepare, at which disclosure to the
    prisoner is made of the evidence being relied upon for the transfer and at which
    an opportunity to be heard in person and to present documentary evidence is
    given”; (3) “An opportunity at the hearing to present testimony of witnesses by
    the defense and to confront and cross-examine witnesses called by the state”; (4)
    5
    See Panetti v. Quarterman, 
    551 U.S. 930
    , 934-35 (2007) (“Under Ford, once a prisoner
    makes the requisite preliminary showing that his current mental state would bar his
    execution, the Eighth Amendment, applicable to the States under the Due Process Clause of
    the Fourteenth Amendment, entitles him to an adjudication to determine his condition.”).

    inmate is financially unable to furnish his own”; and (7) “Effective and timely
    notice of all the foregoing rights.”

    Morrissey, 408 U.S. at 489
    (listing elements of due process for parole revocations). If these elements of
    due process are constitutionally required before a state may revoke a former
    prisoner’s parole (Morrissey) or involuntarily hospitalize and treat a prisoner for
    mental illness (Vitek), certainly they are guaranteed to a prisoner who has made
    a plausible showing of mental retardation before he may be declared mentally
    fit and eligible for execution.
    The Court’s decisions, especially Vitek, Morrissey, and Wolff, clearly
    indicate that Pierce, who made a prima facie showing that he is mentally
    retarded, is entitled to have his condition adjudicated in a contradictory
    evidentiary hearing in which he has an opportunity to present testimony of
    witnesses and to confront and cross-examine witnesses called by the state. The
    state courts plainly failed to provide Pierce with these constitutional procedures
    required by due process. Because Pierce’s liberty interest at issue here arises
    directly from the Constitution itself, and not from an expectation or interest
    created by state laws or policies, his case invokes the full due process protections
    established by Vitek and Morrissey and does not call for the additional step of
    applying the framework established in Mathews v. Eldridge, 
    424 U.S. 319
    (1976).6 Moreover, application of Mathews here serves only to confirm that all
    of the due process essentials set forth in Morrissey are required in this case. The

    Under the Mathews balancing test, we weigh “[f]irst, the private interest that will be
    affected by the official action; second, the risk of an erroneous deprivation of such interest
    through the procedures used, and the probable value, if any, of additional or substitute
    procedural safeguards; and finally, the Government’s interest, including the function involved
    and the fiscal and administrative burdens that the additional or substitute procedural
    requirement would entail.” 
    Id. at 335.

    private interest that will be affected by the official action here, Pierce’s life, is,
    of course, maximal. The risk of an erroneous deprivation of such an interest
    through lesser procedures than those established by Morrissey is intolerably
    great, and the value of requiring additional procedural safeguards is
    extraordinarily high. Consequently, the government’s interest in avoiding the
    cost of additional process, including the function involved and the fiscal and
    administrative burdens that the additional or substitute procedural
    requirements would entail, is relatively small and does not outweigh the other
    considerations involved or justify a lesser level of process.7
    Under AEDPA, a federal court may grant habeas relief only if the state
    court’s adjudication of the claim on the merits “resulted in a decision that was
    contrary to, or involved an unreasonable application of, clearly established
    Federal law, as determinated by the Supreme Court of the United States,” or
    “resulted in a decision that was based on an unreasonable determination of the
    facts in light of the evidence presented in the State court proceeding.” 28 U.S.C.
    § 2254(d). “When a state court’s adjudication of a claim is dependent on an
    antecedent unreasonable application of federal law, the requirement set forth in
    28 U.S.C. § 2254(d)(1) is satisfied. A federal court must then resolve the claim
    without the deference AEDPA otherwise requires.”

    (citing Wiggins v. Smith, 
    539 U.S. 510
    , 527-29, 534 (2003)). “Here, due to the

    It bears emphasis, moreover, that Pierce is one of the few Texas death row inmates
    who has not been afforded such a full due process hearing in a post-Atkins case. Starting with
    Ex parte Briseno, 
    135 S.W.3d 1
    (Tex. Crim. App. 2004), in which the Texas Court of Criminal
    Appeals implemented the Supreme Court’s pronouncements in Atkins, the prisoner was
    granted a live hearing on remand in state trial court to determine whether he was mentally
    retarded. As Judge Higginbotham observed, “Texas courts quickly found their footing
    post-Atkins. . . . Briseno was also convicted before Atkins but . . . received a five-day
    evidentiary hearing on his post-Atkins habeas claim of mental retardation.” 
    Hall, 534 F.3d at 389
    (Higginbotham, J., concurring in part and dissenting in part) (citing 
    Briseno, 135 S.W.3d at 4
    ). Such live hearings have become the norm in Atkins cases in the Texas state courts. See
    Sarah Gail Tuthill, Comment, The Texas-Size Struggle to Implement Atkins v. Virginia, 14 Tex.

    of procedural approaches).

    state court’s unreasonable application of [Atkins, Vitek, Morrissey, and Wolff,]
    the factfinding procedures upon which the court relied were ‘not adequate for
    reaching reasonably correct results’ or, at a minimum, resulted in a process that
    appeared to be “‘seriously inadequate for the ascertainment of the truth.’” 
    Id. at 954
    (quoting 
    Ford, 477 U.S. at 423-424
    (Powell, J., concurring in part and
    concurring in judgment)).
    III.
    For these reasons, in my view, the judgment of the federal district court
    deferring to the state courts’ rulings on Pierce’s mental condition should be
    vacated and the case should be remanded in part to the district court with
    directions to consider Pierce’s Atkins claim on the merits in an adversarial
    evidentiary hearing in accordance with the foregoing due process principles and
    without deferring to the state courts’ findings.
